The Science of Heredity

Chapter 5: Genetics- The Science of Heredity
Big Idea: 
Organisms produced by sexual reproduction inherit half their DNA from each parent. The new combination of DNA determines an organism's traits. 
Essential Questions:
  • What controls the inheritance of traits in organisms?
  • What is the probability and how does it help explain the results of genetic crosses?
  • What role do chromosomes play in inheritance?
  • What forms the genetic code?
Topics:
  1. Mendel's Work
  2. Probability and Heredity
  3. The Cell and Inheritance
  4. Genes, DNA and Proteins
Investigations: 

Modern Genetics

Chapter 6: Modern Genetics
 
Big Idea
A person's traits depend on which alleles are inherited from each parent, how those alleles work together, and environmental factors. 
 
Essential Questions:
  • What are some patterns of inheritance in humans?
  • How do geneticists trace the inheritance of traits?
  • What are three ways of producing organisms with desired traits?
 
Topics:
  1. Human Inheritance
  2. Human Genetic Disorders
  3. Advances in Genetics

Changes Over Time

Chapter 7: Changes Over Time
 
Big Idea
Genetic variation and environmental factors have together resulted in the evolution of species.
 
Essential Questions:
  • How does natural selection lead to evolution?
  • What evidence supports the theory of evolution?
  • What factors have contributed to the diversity of species?
  • How does a branching tree diagram show evolutionary relationships?
Topics:
  1. Darwin's Theory
  2. Evidence of Evolution
  3. Evolution of Species
  4. Classifying Organisms
  5. Branching Trees
Investigations:

Earth's History

Chapter 8: Earth's History
 
Big Idea
Evidence from rocks shows that life has existed for billions of years and how Earth has changed over time. 
 
Essential Questions:
  • How do geologists determine the relative age of rocks?
  • How does the theory of plate tectonics explain the movement of Earth's landmasses?
  • What were the major events of the Paleozoic, Mesozoic, and Cenozoic Eras?
 
Topics:
  1. The Rock Cycle
  2. The Relative Age of Rocks
  3. Radioactive Dating
  4. Movement of Earth's Plates
  5. The Geologic Time Scale
